The way I would fix it would be to just add aluminum weld until there is enough the to shape then I would re-drill the hole out again it shouldn't take more then an hour or so. What's the theory on why it broke? My offer still stands too, if you want to cover shipping I will gladly do it.

no theroies, unless while it was riding home with me in my old company car and i hit a big ass bump and the mount broke... or on the one trip i've made with it in my dads truck bed for 3 miles it broke there. highly doubtful on either case, as the fracture surface looks to be worn down and quite older.

but i think i might just have to take you up on this offer corn. have you welded on these cases before i assume?

Little_Horse · « **Reply #52 on:** April 28, 2010, 07:24:33 AM »

I havent welded a 750 case, but I have alot of experience welding aluminum since I thats my profession. Also used to weld up bike frames for a bit. A month ago I welded up two quarter sized holes that were on the case of a TS250 dirt bike, chalk that one up to another vintage bike back on the road. Welding up engine cases it is important that where you weld on it it is strong enough by itself not to warp. Considering that yours is the mount itself I feel that there is very little chance for problems. Honda designed it to be strong there. Then it is just a matter of getting it spotless so the weld doesn't contaminate and you are good to go.

awesome! ya i'm pretty sure everything else is ok to go as far as welding it up, i just need to get the case up to you!! that's awesome you can do this, especially for free!!! always good to know there's good people out there who appreciate the work and not wasting old parts!! thanks again man!

No problem man, I am going to PM you with my address, you can ship it when ever you like.

ok guys, so if i want to run 4th over pistons from Z1, what kind of tuning adjustments can i expect to preform? thanks!

You might PM Hondaman, he has worked with those many times and probably has a quick list he can send you.

I pm'd mark and he recommended i go up a size on the main jet, from a 115-120. i'm curious if the middle needle position is good?? i REALLY don't want to have to take these carbs back apart to adjust the needles again, it's kind of a pain... i'm at about 600 feet and i will be running a carpy 4-1 and a K&N filter in the stock airbox... thanks guys!

wannabridin · « **Reply #58 on:** May 04, 2010, 08:00:26 AM »

well, here's where i stand now with the carbs. i have to order some new jets, 120's and do a final cleaning and spraying to get all the dirt and grime that might have entered while sitting on the bench. also, i had to come up with a unique way of getting the choke assembly to work, since when i bought the carbs, the choke levers were a bit stressed and therefore broke easily while handling. i didn't have the necessary hardware for the assembly, so i was missing the lever, springs and cable w/ holder, so what i did was weld up the two halves together and now they all turn in unison. i used some of the green o-rings that nikki-six provided (thank you!!) in place of the felt o-rings, and these help keep the choke where i need it when it's open or closed. sorry for the crappy iphone pics, it was pretty late and i didn't feel like searching for my camera...

since i'm going with silver and red for the paint scheme, i decided to get some red fuel line, which looks pretty dang cool if you ask me!

Zaipai · « **Reply #59 on:** May 05, 2010, 04:30:11 PM »

Very creative with the choke setup.. Probably the way Honda should have done it the first time.

Those pic's are not crappy they are pretty good. Want to see crappy, let me show you some pics from my Samsung phone..

I like the red fuel lines!

wannabridin · « **Reply #61 on:** May 06, 2010, 06:37:03 AM »

well, crappy as there's no macro feature on the iphone 3g... and thanks corn, i like the lines too!! i'm going to run them from the tank to the carbs, and then use have the drain lines the same! should be a nice little touch!!

ok, so i'm having serious issues with these float bowls. i've had to drill and re-tap 7 of the a/f screw size of the float bowl threads to accept a M5x.8mm bolt. when i was reinstalling the float bowls for the first time after opening them up, the new stainless hardware i'm using wouldn't catch enough threads on the bottom, and the bores were clean of all debris!! so i had to re-tap them for bigger hardware, it's SUCH a PITA!!! oh well, hopefully i can get these all buttoned up and they wont leak, i'm ready for them to be back together and ready to go on the bike!!!

Little_Horse · « **Reply #62 on:** May 06, 2010, 07:20:50 AM »

The original screws suck anyways its worth the time to upgrade to stainless and larger hardware, once done you should never have to mess with stripped philips head screws anymore. Are you going to use button head allen bolts?

well i bought a kit from stainless cycle for their stainless hex head screws, ust the standard ones. but for the enlarged holes, i'm going with some button head 5mm x .8mm stainless hex heads. i agree the stock phillips heads suck! i'm going to use hex heads wherever i can on this build. hell, i even replaced the needle retainers and the butterfly screws with button hex heads!!

not to mention the backing plate screws with button heads!!

wannabridin · « **Reply #65 on:** May 06, 2010, 12:40:33 PM »

hey guys. for the PD carbs i'm using, would these jets work? they look just like what i have, just want to check!

http://www.z1enterprises.com/detail.aspx?ID=1924

also, do i have the 5 or 6 mm vac sync adapters? are these something that stay on permanently?

5mm: http://www.z1enterprises.com/detail.aspx?ID=3263
6mm: http://www.z1enterprises.com/detail.aspx?ID=3262

which one?

wannabridin · « **Reply #66 on:** May 07, 2010, 09:53:44 AM »

anyone??

Little_Horse · « **Reply #67 on:** May 07, 2010, 10:05:22 AM »

I don't know about the jets, but at jetsrus.com they give the dimensions of the different jets so you can make sure then use their number to cross reference the jet you linked for us. I don't know any other way to help because there are still quite a few different round jets by keihin and they sometimes are only a mm different in height or diameter, better to be sure I guess.

wannabridin · « **Reply #68 on:** May 11, 2010, 08:33:33 PM »

guys, are there anything else i can do to the carbs before i put them on the bike to squeeze out everything they're capable of?? i read somewhere on here about someone putting the needles and something else from a K into F carbs, but i was wondering if there was anything else i could do to make sure these are running top notch once they're dialed in.

next up is the restoring of the head-to-carbs and carbs-to-airbox rubbers. then a nice clean up of the stock airbox, and i might paint it. might do it silver with the grooves painted red. i'm not sure yet! also, what can i do to the airbox to bring the most out of it? i'm going to run a K&N filter in there.

Little_Horse · « **Reply #69 on:** May 11, 2010, 09:09:22 PM »

if they are already clean and bench synced there is nothing for you to do but put them on test then adjust as needed which usually means removing them a few times until it runs right.

wannabridin · « **Reply #70 on:** May 12, 2010, 06:20:01 AM »

i figured that, just wanted to see if there was anything i could do, little tricks of the trade, to snag as much performance out of them as i could! i'm pretty sure the "bench sync" is still good because i never touched them after i received them. all the slides seem to move uniformly, and they all appear to be at the same height when closed.

Little_Horse · « **Reply #71 on:** May 12, 2010, 04:08:18 PM »

It still doesn't hurt to sync them afterward. I built a vacuum gauge setup for $30 with 4 gauges off of ebay and some brass fittings. I used to have a motion pro but I hated it. I took the reducers from that and put them in the hoses of my setup to eliminate gauge flutter. By the way it works great on everything two cylinder 3 and 4 and if I ever land a cbx I can just add two more gauges.

wannabridin · « **Reply #72 on:** May 13, 2010, 06:03:58 AM »

ya, i'll sync it as best i can when it's all hooked up. i bit the bullet and bought a Morgan with their 80 degree screwdriver. i got a good deal on the whole thing, and i have another bike that could use a fresh sync. i also dug out the dwell meter, so once the motor is up and running again, that'll help me be pretty dead on with my RPM's

wannabridin · « **Reply #73 on:** June 03, 2010, 09:27:27 AM »

well, looks like the project will be on a "hold" for awhile. i need to do some work on my mustang (1966 coupe, 289, 4V, 4-spd) because one of my best friends asked me to drive him and his fiancee off in it after the ceremony. basically, i need to get the clutch back and working properly, the rear suspension sorted out and the exhaust leak fixed. so that's 5-600 that COULD go towards the bike... i'm only thinking a couple months with just doing the "free" stuff, then i can get back focused in on it! i hope... this sucks, but the mustang was and always will be my first "baby" so when she needs attention, she gets it!

Zaipai · « **Reply #74 on:** June 04, 2010, 08:30:14 PM »

Yeah, bud I hear ya.. Gotta take care of things as they need to be taken care of.. GL with the Tang and Keep us posted on any progress on the build..
